Configure the PSU for 310V output i.e. 2 white wires from the mains transformer.
DISCONNECT THE AMPLIFIER FROM THE MAINS BEFORE BEGINNING.
If the unit has been used recently, allow sufficient time for the power supply capacitors to discharge before beginning (5 mins is usually sufficient).
This is a two stage conversion. Stage 1 disables the on-board high voltage supply and connects the new off-board supply. Stage 2 enables remote switching of the new supply from the amplifiers on-off switch.
Connect the RED wire to Pin 8 of the OCTAL (GZ34) valve base. Make sure that no other connections to this point are disturbed.
Connect the GREEN wire to the -ve terminal (usually coloured Black) of the large electrolytic can type capacitor furthest to the back of the amp.
4. Short out R21. This can conveniently be done by connecting the (Red and Yellow?) +ve terminals of the same capacitor together.
